Hello "twity"-
You have been told before that we have a policy on screen names here at JavaRanch. Basically, it must consist of a first name, a space, and a last name, and not be obviously fictitious. Since yours does not conform with it, please take a moment to change it, which you can do right here. This is not optional - accounts without a proper screen name are generally closed. Change it before your next post.
As to your question, do you want to overwrite an existing file without deleting it first? That can be done by using a FileWriter (or FileOutputStream), and setting the boolean "append" to false in the constructor.
If it's something else youre looking for, post some more detail about the question.

Hello Twity!
First, please change your display name, as Ulf has asked you!
After you changed your name, have a look at the API documentation of class java.io.File. It contains the methods you're looking for.
